EASA AIRWORTHINESS DIRECTIVE
AD No.: 2012-0026
Date: 08 February 2012
Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation
(EC) No 216/2008 on behalf of the European Community, its Member States and of the European
third countries that participate in the activities of EASA under Article 66 of that Regulation
This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the
continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate
an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency
[EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].
Type Approval Holder’s Name : AIRBUS
Type/Model designation(s) :A380 aeroplanes
TCDS Number: EASA.A.110
Foreign AD: Not applicable
Supersedure: This AD supersedes EASA AD 2012-0013 dated 20 January 2012.
ATA 57 Wings – Wing Rib Foot – InspectionManufacturer(s): Airbus
Applicability:
Airbus A380-841, A380-842, and A380-861 aeroplanes, all serial numbers.
Reason: Following an unscheduled internal inspection of an A380 wing, some rib feet
have been found with cracks originating from the rib to skin panel attachment
holes (Type 1 cracks according to Airbus All Operator Telex (AOT) terminology).
Further to this finding, inspections were carried out on a number of other
aeroplanes confirming the existence of these cracks. During one of those
inspections, a new form of rib foot cracking originating from the forward and aft
edges of the vertical web of the rib feet has been identified (Type 2 cracks
according to Airbus AOT terminology). This condition, if not detected and
corrected, may lead to reduction of the structural integrity of the aeroplane.
EASA AD 2012-0013 required Detailed Visual Inspections (DVI) to detect cracks
on the wing rib feet and required as well to repair them when applicable.
Following issuance of EASA AD 2012-0013 it has been confirmed that Type 2
cracks may develop on other aeroplanes after a period of time of service.
For the reasons described above, this AD, which supersedes EASA AD 2012-
0013, extends the applicability to all aeroplane serial numbers and requires
accomplishment of High Frequency Eddy Current (HFEC) inspections of certain
wing rib feet and accomplishment of applicable corrective actions. This AD also
requires that the inspection results are reported to Airbus.
This AD is considered to be a further interim action to address this condition. As
a result of the on-going investigation, further mandatory actions may be
necessary.
Effective Date: 13 February 2012
Required
Action(s) and
Compliance
Time(s):
Required as indicated, unless already accomplished:
(1) Within the compliance time defined in Table 1 of this AD, as applicable,
depending on the number of flight cycles (FC) accumulated by the
aeroplane at the effective date of this AD, accomplish HFEC inspection of
the Left Hand and Right Hand wings in accordance with the instructions of
Airbus AOT A380-57-8058 revision 1.
Table 1

accumulated since
aeroplane first flight
Compliance time for the HFEC
inspection
Aeroplane has accumulated
less than 1 216 FC
Before or upon accumulation of 1 300 FC

Within 6 weeks or 84 FC, whichever
occurs first after the effective date of this
AD
Aeroplane has accumulated
1 384 FC or more
No later than 3 weeks after the effective
date of this AD
(2) If any crack is detected during the
HFEC inspections required by paragraph
(1) of this AD, before next flight, contact Airbus for approved instructions and
accomplish those instructions accordingly within the specified compliance
time.
(3)
Within 2 days after accomplishment of the HFEC inspections as required by
paragraph (1) of this AD, report inspection results (including no findings) to
Airbus.

I've been browsing online more than 3 hours lately, yet I never found any fascinating article like yours. It's beautiful value enough for me. In my view, if all website owners and bloggers made excellent content as you probably did, the web might be much more useful than ever before.
